ca2c565a7c ksmbd: retry iterate_dir in smb2_query_dir
[ Upstream commit 2b904d61a97e8ba79e3bc216ba290fd7e1d85028 ]

Some file systems do not ensure that the single call of iterate_dir
reaches the end of the directory. For example, FUSE fetches entries from
a daemon using 4KB buffer and stops fetching if entries exceed the
buffer. And then an actor of caller, KSMBD, is used to fill the entries
from the buffer.
Thus, pattern searching on FUSE, files located after the 4KB could not
be found and STATUS_NO_SUCH_FILE was returned.

42de603783 bpf: fix potential error return
[ Upstream commit c4441ca86afe4814039ee1b32c39d833c1a16bbc ]

The bpf_remove_insns() function returns WARN_ON_ONCE(error), where
error is a result of bpf_adj_branches(), and thus should be always 0
However, if for any reason it is not 0, then it will be converted to
boolean by WARN_ON_ONCE and returned to user space as 1, not an actual
error value. Fix this by returning the original err after the WARN check.

ced1bd9297 sound: usb: format: don't warn that raw DSD is unsupported
[ Upstream commit b50a3e98442b8d72f061617c7f7a71f7dba19484 ]

UAC 2 & 3 DAC's set bit 31 of the format to signal support for a
RAW_DATA type, typically used for DSD playback.

This is correctly tested by (format & UAC*_FORMAT_TYPE_I_RAW_DATA),
fp->dsd_raw = true; and call snd_usb_interface_dsd_format_quirks(),
however a confusing and unnecessary message gets printed because
the bit is not properly tested in the last "unsupported" if test:
if (format & ~0x3F) { ... }

For example the output:

usb 7-1: new high-speed USB device number 5 using xhci_hcd
usb 7-1: New USB device found, idVendor=262a, idProduct=9302, bcdDevice=0.01
usb 7-1: New USB device strings: Mfr=1, Product=2, SerialNumber=6
usb 7-1: Product: TC44C
usb 7-1: Manufacturer: TC44C
usb 7-1: SerialNumber: 5000000001
hid-generic 0003:262A:9302.001E: No inputs registered, leaving
hid-generic 0003:262A:9302.001E: hidraw6: USB HID v1.00 Device [DDHIFI TC44C] on usb-0000:08:00.3-1/input0
usb 7-1: 2:4 : unsupported format bits 0x100000000

This last "unsupported format" is actually wrong: we know the
format is a RAW_DATA which we assume is DSD, so there is no need
to print the confusing message.

This we unset bit 31 of the format after recognizing it, to avoid
the message.

7815958273 ALSA: hda/realtek: Add new alc2xx-fixup-headset-mic model
[ Upstream commit 50db91fccea0da5c669bc68e2429e8de303758d3 ]

Introduces the alc2xx-fixup-headset-mic model to simplify enabling
headset microphones on ALC2XX codecs.

Many recent configurations, as well as older systems that lacked this
fix for a long time, leave headset microphones inactive by default.
This addition provides a flexible workaround using the existing
ALC2XX_FIXUP_HEADSET_MIC quirk.

1ea629e7bb btrfs: flush delalloc workers queue before stopping cleaner kthread during unmount
[ Upstream commit f10bef73fb355e3fc85e63a50386798be68ff486 ]

During the unmount path, at close_ctree(), we first stop the cleaner
kthread, using kthread_stop() which frees the associated task_struct, and
then stop and destroy all the work queues. However after we stopped the
cleaner we may still have a worker from the delalloc_workers queue running
inode.c:submit_compressed_extents(), which calls btrfs_add_delayed_iput(),
which in turn tries to wake up the cleaner kthread - which was already
destroyed before, resulting in a use-after-free on the task_struct.

Syzbot reported this with the following stack traces:

465b18e1c5 drm/amdkfd: Correct the migration DMA map direction
[ Upstream commit 5c3de6b02d38eb9386edf50490e050bb44398e40 ]

The SVM DMA device map direction should be set the same as
the DMA unmap setting, otherwise the DMA core will report
the following warning.

Before finialize this solution, there're some discussion on
the DMA mapping type(stream-based or coherent) in this KFD
migration case, followed by https://lore.kernel.org/all/04d4ab32
-45a1-4b88-86ee-fb0f35a0ca40@amd.com/T/.

As there's no dma_sync_single_for_*() in the DMA buffer accessed
that because this migration operation should be sync properly and
automatically. Give that there's might not be a performance problem
in various cache sync policy of DMA sync. Therefore, in order to
simplify the DMA direction setting alignment, let's set the DMA map

c217d67b29 wifi: mac80211: wake the queues in case of failure in resume
[ Upstream commit 220bf000530f9b1114fa2a1022a871c7ce8a0b38 ]

In case we fail to resume, we'll WARN with
"Hardware became unavailable during restart." and we'll wait until user
space does something. It'll typically bring the interface down and up to
recover. This won't work though because the queues are still stopped on
IEEE80211_QUEUE_STOP_REASON_SUSPEND reason.
Make sure we clear that reason so that we give a chance to the recovery
to succeed.

66376f1a73 btrfs: fix use-after-free when COWing tree bock and tracing is enabled
[ Upstream commit 44f52bbe96dfdbe4aca3818a2534520082a07040 ]

When a COWing a tree block, at btrfs_cow_block(), and we have the
tracepoint trace_btrfs_cow_block() enabled and preemption is also enabled
(CONFIG_PREEMPT=y), we can trigger a use-after-free in the COWed extent
buffer while inside the tracepoint code. This is because in some paths
that call btrfs_cow_block(), such as btrfs_search_slot(), we are holding
the last reference on the extent buffer @buf so btrfs_force_cow_block()
drops the last reference on the @buf extent buffer when it calls
free_extent_buffer_stale(buf), which schedules the release of the extent
buffer with RCU. This means that if we are on a kernel with preemption,
the current task may be preempted before calling trace_btrfs_cow_block()
and the extent buffer already released by the time trace_btrfs_cow_block()
is called, resulting in a use-after-free.

Fix this by moving the trace_btrfs_cow_block() from btrfs_cow_block() to
btrfs_force_cow_block() before the COWed extent buffer is freed.
This also has a side effect of invoking the tracepoint in the tree defrag
code, at defrag.c:btrfs_realloc_node(), since btrfs_force_cow_block() is
called there, but this is fine and it was actually missing there.

Rename and export __btrfs_cow_block() as btrfs_force_cow_block(). This is
to allow to move defrag specific code out of ctree.c and into defrag.c in

eba25e21dc ila: serialize calls to nf_register_net_hooks()
[ Upstream commit 260466b576bca0081a7d4acecc8e93687aa22d0e ]

syzbot found a race in ila_add_mapping() [1]

commit 031ae72825ce ("ila: call nf_unregister_net_hooks() sooner")
attempted to fix a similar issue.

Looking at the syzbot repro, we have concurrent ILA_CMD_ADD commands.

Add a mutex to make sure at most one thread is calling nf_register_net_hooks().

[ Upstream commit f91a5b8089389eb408501af2762f168c3aaa7b79 ]

Blamed commit forgot MSG_PEEK case, allowing a crash [1] as found
by syzbot.

Rework vlan_get_protocol_dgram() to not touch skb at all,
so that it can be used from many cpus on the same skb.

Add a const qualifier to skb argument.

d91b4a9baa af_packet: fix vlan_get_tci() vs MSG_PEEK
[ Upstream commit 77ee7a6d16b6ec07b5c3ae2b6b60a24c1afbed09 ]

Blamed commit forgot MSG_PEEK case, allowing a crash [1] as found
by syzbot.

Rework vlan_get_tci() to not touch skb at all,
so that it can be used from many cpus on the same skb.

Add a const qualifier to skb argument.

81d26fee2c net: wwan: iosm: Properly check for valid exec stage in ipc_mmio_init()
[ Upstream commit a7af435df0e04cfb4a4004136d597c42639a2ae7 ]

ipc_mmio_init() used the post-decrement operator in its loop continuing
condition of "retries" counter being "> 0", which meant that when this
condition caused loop exit "retries" counter reached -1.

But the later valid exec stage failure check only tests for "retries"
counter being exactly zero, so it didn't trigger in this case (but
would wrongly trigger if the code reaches a valid exec stage in the
very last loop iteration).

Fix this by using the pre-decrement operator instead, so the loop counter
is exactly zero on valid exec stage failure.

ac9cfef695 net: reenable NETIF_F_IPV6_CSUM offload for BIG TCP packets
[ Upstream commit 68e068cabd2c6c533ef934c2e5151609cf6ecc6d ]

The blamed commit disabled hardware offoad of IPv6 packets with
extension headers on devices that advertise NETIF_F_IPV6_CSUM,
based on the definition of that feature in skbuff.h:

 *   * - %NETIF_F_IPV6_CSUM
 *     - Driver (device) is only able to checksum plain
 *       TCP or UDP packets over IPv6. These are specifically
 *       unencapsulated packets of the form IPv6|TCP or
 *       IPv6|UDP where the Next Header field in the IPv6
 *       header is either TCP or UDP. IPv6 extension headers
 *       are not supported with this feature. This feature
 *       cannot be set in features for a device with
 *       NETIF_F_HW_CSUM also set. This feature is being
 *       DEPRECATED (see below).

The change causes skb_warn_bad_offload to fire for BIG TCP
packets.

BIG TCP introduced an IPV6_TLV_JUMBO IPv6 extension header to
communicate packet length, as this is an IPv6 jumbogram. But, the
feature is only enabled on devices that support BIG TCP TSO. The
header is only present for PF_PACKET taps like tcpdump, and not
transmitted by physical devices.

For this specific case of extension headers that are not
transmitted, return to the situation before the blamed commit
and support hardware offload.

ipv6_has_hopopt_jumbo() tests not only whether this header is present,
but also that it is the only extension header before a terminal (L4)
header.

94dde4fd7e net: llc: reset skb->transport_header
[ Upstream commit a024e377efed31ecfb39210bed562932321345b3 ]

802.2+LLC+SNAP frames received by napi_complete_done with GRO and DSA
have skb->transport_header set two bytes short, or pointing 2 bytes
before network_header & skb->data. As snap_rcv expects transport_header
to point to SNAP header (OID:PID) after LLC processing advances offset
over LLC header (llc_rcv & llc_fixup_skb), code doesn't find a match
and packet is dropped.

Between napi_complete_done and snap_rcv, transport_header is not used
until __netif_receive_skb_core, where originally it was being reset.
Commit fda55eca5a ("net: introduce skb_transport_header_was_set()")
only does so if not set, on the assumption the value was set correctly
by GRO (and also on assumption that "network stacks usually reset the
transport header anyway"). Afterwards it is moved forward by
llc_fixup_skb.

Locally generated traffic shows up at __netif_receive_skb_core with no
transport_header set and is processed without issue. On a setup with
GRO but no DSA, transport_header and network_header are both set to
point to skb->data which is also correct.

As issue is LLC specific, to avoid impacting non-LLC traffic, and to
follow up on original assumption made on previous code change,
llc_fixup_skb to reset the offset after skb pull. llc_fixup_skb
assumes the LLC header is at skb->data, and by definition SNAP header
immediately follows.

This issue occurs because the skb buffer is too small, and it's actual
allocation is aligned. This hides an actual issue, which is that nr_route_frame
does not validate the buffer size before using it.

Fix this issue by checking skb->len before accessing any fields in skb->data.

19bbca7bc5 ipip,ip_tunnel,sit: Add FOU support for externally controlled ipip devices
[ Upstream commit ac931d4cde ]

Today ipip devices in collect-metadata mode don't allow for sending FOU
or GUE encapsulated packets. This patch lifts the restriction by adding
a struct ip_tunnel_encap to the tunnel metadata.

On the egress path, the members of this struct can be set by the
bpf_skb_set_fou_encap kfunc via a BPF tc-hook. Instead of dropping packets
wishing to use additional UDP encapsulation, ip_md_tunnel_xmit now
evaluates the contents of this struct and adds the corresponding FOU or
GUE header. Furthermore, it is making sure that additional header bytes
are taken into account for PMTU discovery.

On the ingress path, an ipip device in collect-metadata mode will fill this
struct and a BPF tc-hook can obtain the information via a call to the
bpf_skb_get_fou_encap kfunc.

The minor change to ip_tunnel_encap, which now takes a pointer to
struct ip_tunnel_encap instead of struct ip_tunnel, allows us to control
FOU encap type and parameters on a per packet-level.

28f1e04d91 net: stmmac: restructure the error path of stmmac_probe_config_dt()
[ Upstream commit 2b6ffcd7873b7e8a62c3e15a6f305bfc747c466b ]

Current implementation of stmmac_probe_config_dt() does not release the
OF node reference obtained by of_parse_phandle() in some error paths.
The problem is that some error paths call stmmac_remove_config_dt() to
clean up but others use and unwind ladder.  These two types of error
handling have not kept in sync and have been a recurring source of bugs.
Re-write the error handling in stmmac_probe_config_dt() to use an unwind
ladder. Consequently, stmmac_remove_config_dt() is not needed anymore,
thus remove it.

This bug was found by an experimental verification tool that I am
developing.

51c8cfd00e net: stmmac: don't create a MDIO bus if unnecessary
[ Upstream commit f3c2caacee824ce4a331cdafb0b8dc8e987f105e ]

Currently a MDIO bus is created if the devicetree description is either:

    1. Not fixed-link
    2. fixed-link but contains a MDIO bus as well

The "1" case above isn't always accurate. If there's a phy-handle,
it could be referencing a phy on another MDIO controller's bus[1]. In
this case, where the MDIO bus is not described at all, currently
stmmac will make a MDIO bus and scan its address space to discover
phys (of which there are none). This process takes time scanning a bus
that is known to be empty, delaying time to complete probe.

There are also a lot of upstream devicetrees[2] that expect a MDIO bus
to be created, scanned for phys, and the first one found connected
to the MAC. This case can be inferred from the platform description by
not having a phy-handle && not being fixed-link. This hits case "1" in
the current driver's logic, and must be handled in any logic change here
since it is a valid legacy dt-binding.

Let's improve the logic to create a MDIO bus if either:

    - Devicetree contains a MDIO bus
    - !fixed-link && !phy-handle (legacy handling)

This way the case where no MDIO bus should be made is handled, as well
as retaining backwards compatibility with the valid cases.

Below devicetree snippets can be found that explain some of
the cases above more concretely.

Here's[0] a devicetree example where the MAC is both fixed-link and
driving a switch on MDIO (case "2" above). This needs a MDIO bus to
be created:

    &fec1 {
            phy-mode = "rmii";

            fixed-link {
                    speed = <100>;
                    full-duplex;
            };

            mdio1: mdio {
                    switch0: switch0@0 {
                            compatible = "marvell,mv88e6190";
                            pinctrl-0 = <&pinctrl_gpio_switch0>;
                    };
            };
    };

Here's[1] an example where there is no MDIO bus or fixed-link for
the ethernet1 MAC, so no MDIO bus should be created since ethernet0
is the MDIO master for ethernet1's phy:

    &ethernet0 {
            phy-mode = "sgmii";
            phy-handle = <&sgmii_phy0>;

            mdio {
                    compatible = "snps,dwmac-mdio";
                    sgmii_phy0: phy@8 {
                            compatible = "ethernet-phy-id0141.0dd4";
                            reg = <0x8>;
                            device_type = "ethernet-phy";
                    };

                    sgmii_phy1: phy@a {
                            compatible = "ethernet-phy-id0141.0dd4";
                            reg = <0xa>;
                            device_type = "ethernet-phy";
                    };
            };
    };

    &ethernet1 {
            phy-mode = "sgmii";
            phy-handle = <&sgmii_phy1>;
    };

Finally there's descriptions like this[2] which don't describe the
MDIO bus but expect it to be created and the whole address space
scanned for a phy since there's no phy-handle or fixed-link described:

    &gmac {
            phy-supply = <&vcc_lan>;
            phy-mode = "rmii";
            snps,reset-gpio = <&gpio3 RK_PB4 GPIO_ACTIVE_HIGH>;
            snps,reset-active-low;
            snps,reset-delays-us = <0 10000 1000000>;
    };

The aging count is not a simple 20-bit value but comprises a 3-bit
multiplier and a 20-bit second time.  The code tries to use the
original multiplier which is 4 as the second count is still 300 seconds
by default.

As the 20-bit number is now too large for practical use there is an option
to interpret it as microseconds instead of seconds.

2478960146 drm/bridge: adv7511_audio: Update Audio InfoFrame properly
[ Upstream commit 902806baf3c1e8383c1fe3ff0b6042b8cb5c2707 ]

AUDIO_UPDATE bit (Bit 5 of MAIN register 0x4A) needs to be set to 1
while updating Audio InfoFrame information and then set to 0 when done.
Otherwise partially updated Audio InfoFrames could be sent out. Two
cases where this rule were not followed are fixed:
 - In adv7511_hdmi_hw_params() make sure AUDIO_UPDATE bit is updated
   before/after setting ADV7511_REG_AUDIO_INFOFRAME.
 - In audio_startup() use the correct register for clearing
   AUDIO_UPDATE bit.

The problem with corrupted audio infoframes were discovered by letting
a HDMI logic analyser check the output of ADV7535.

Note that this patchs replaces writing REG_GC(1) with
REG_INFOFRAME_UPDATE. Bit 5 of REG_GC(1) is positioned within field
GC_PP[3:0] and that field doesn't control audio infoframe and is read-
only. My conclusion therefore was that the author if this code meant to
clear bit 5 of REG_INFOFRAME_UPDATE from the very beginning.

[ Upstream commit ce1219c3f76bb131d095e90521506d3c6ccfa086 ]

Currently, we don't use the return value from sock_queue_rcv_skb, which
means we may leak skbs if a message is not successfully queued to a
socket.

Instead, ensure that we're freeing the skb where the sock hasn't
otherwise taken ownership of the skb by adding checks on the
sock_queue_rcv_skb() to invoke a kfree on failure.

In doing so, rather than using the 'rc' value to trigger the
kfree_skb(), use the skb pointer itself, which is more explicit.

Also, add a kunit test for the sock delivery failure cases.
